A

LIST OF

ARACHNIDA FROM

HAYTI,

WITH

DESCRIPTIONS OF

NEW

SPECIES.

BY NATHAN BANKS.

During

the springof 1899 Mr. R. J.

Crew

collected

some

spiders in Hayti, mostly

from

the vicinity of Port-au-Prince. Comparatively

few

spiders

have

been recorded

from

thisisland,

and many

ofthese are

from

other parts

and

are large spiders. According to

my

instructions Mr.

Crew

collected the smaller species,

and

thus secured a

number

of

new

forms, as well as others

unknown from

the region.

In all 63 spiders

and

3 Phalangids weretaken.

The

Epeiridce with 17species

and

the Attidse with 15 species are

more

fullyrepresented

than

the otherfamilies.

Most

ofthe spiders are

known

only

from

the

West

Indies,

but

about 17 species occur also in the southern United States.

The follomng
